Well this whole increasing the dosages has to remain to be seen as user dependent. I don't know if you were bulking or cutting in that cylce. Cutting and increasing the dose really can be harder to see a big difference because of the caloric intake difference compared to a bulking surplus. No one should be increasing their doses just for the fun of it. There has to be a genuine plateau. A plateau in strength in the gym and/or physical gains and/or leaness desired. This is all assuming you are doing EVERYTHING you're supposed to be doing in regards to diet and training while trying to break this plateau. If you are cutting and you plateau you don't eat more. You adjust the ratios of food per meal and perhaps your cardio routine even. Then you can bump up 250mg for example.
I'm not saying is that higher doses are not 'where it's at' and that everyone should increase their dose. I'm saying that if you increase your dose, you SHOULD be able to break your plateau. You don't go week to week wondering if this week you'll need to up doses. When you get 'there' you'll know when and how. This information should pertain to guys that are doing this sport to compete and maybe for those guys that just do it for themselves. You gotta be very hardcore dedicated to this lifestyle. If you are not 100% dedicated to diet, training and supps then you are not going to get back what you put in to this sport. Yea there are risks, but to get that edge on someone else sometimes you gotta do what you gotta do.
